JACOB I-I. GMELIN, OF VEST BAY CITY, MICHIGAN.

GOAL SCREENER AND BAGGER.

SPECIFICATION forming part of Letters Patent No. 7d1,398, dated October 13, 1903.

Application filed September 23, 1902. Serial No. 124,556. (No model.)

To all whom it may concern:

Be it known that I, J Acon H. GMELIN, a citizen of the United States, residing at West Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Coal Screeners and Baggers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a combined coal screener and bagger.

The improvements consist in the construction and arrangement of a coal screener and bagger, carrying-bags, or other suitable receptacles mounted on a movable framework and having means arranged in compact form for screening and grading the coal and for depositing the various grades in their respective bags. The device is also provided with a delivery-chute having means for baffling or retarding the flow of coal to prevent its breakage. Another feature of the device is a bar-screen having means for easily adjusting the distance between the bars and for holding them firmly in place when adjusted.

The device is illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the machine. Fig. 2 is a rear elevation in perspective. Fig. 3 is afront elevation in perspective. Fig. 1 is a detail showing the method of attaching the device for spacing the bars of the bar-screen. Fig. 5 is a detail in perspective of the clip for fixing the space between the bars.

Similar numerals refer to similar parts throughout the several viewsf The framework 1 carries the screening and bagging mechanism, the construction and operation of which are as follows:

The machine is placed at the side of a coalcar and the coal is shoveled from the car into the hopper 2, which delivers it to the inclined bar-screen 3, which in turn delivers the large lumps through the chute 4:, which is nearly in line with the screen, into the bag 12 or other suitable receptacle supported by the bag-holder 11. The coal passing through the screen 3 drops upon the trough or apron 6 below the screen and nearly parallel with it and thence is delivered to the top of the screen 7, made of wire mesh or other suitable material and located below but inclined in the opposite direction to the screen 3. This screen 7 in turn delivers the larger lumps by Way of the spout 8 to the bag 12, which in filling is supported by the bag-holder 11. The screenings or fine coal passing through the screen 7 are delivered through the spout 10, which is' inclined transversely to the screen 7, into the bag 12*, supported by the bag -holder 11. The screenings that pass through the upper part of the screen 7 are deflected by the apron 9 into the trough 10.

As is shown in Figs. 2 and 4c the bars forming the screen 3 are mounted on rods 3 and are transversely movable thereon. The rods are supported by the framework 1. The space between the bars is fixed by the clips 3. (Shown in detail in Fig. 5.) These clips consist of strips of metal 3* cylindrical in shape to take the rod 3. The clips have their ends bent outward to form lips 3, which are slightly separated to allow the insertion of a chisel or other tool for opening the clip, so thatit can be removed from the rod 3. By the use of clips of difierent widths the space between the bars of the screen may be altered with ease to screen the coal to any desired degree of fineness.

The chute 4: is provided with wings 5, preferably made of sheet metal, and secured at one end to the chute by riveting or otherwise, the Wings being bent inward toward the center of the chute, so as to retard the coal by deflecting it alternately toward opposite sides of the chute. The second screen 7 may be made of wire or other suitable material attached to a removable frame 14, so that it may be easily and quickly taken out and replaced by another of different mesh.

The frame 1 is preferably mounted on wheels 13, so that it may be easily moved the length of the car as the unloading progresses.

By the means herein described I have produced a coal screener and bagger which is light, compact, and easily movable,which carries with it the bags or other receptacles for receiving the sorted coal, which is provided with a chute for delivering the large coal slowly without breakage, which has means for quickly changing the degree of fineness to which the coal is screened, and which may be placed beside a car and moved along as men shoveling the coal into the hopper work from one end of the car to the other, the machine sorting and delivering it into bags as they proceed.

What I claim as my invention, and wish to secure by Letters Patent, is

A machine for screening and bagging coal comprisingin combination supporting-framework movably mounted on wheels; a hopper carried on the top of the framework; a stationary inclined bar-screen below the hopper, said screen comprising parallel inclined bars, rods through the ends of said bars, removable spring-clips on said rods for fixing the space between the bars, each clip formed of a metal strip bent to encircle the rod and having its ends turned outwardly to form slightlyseparated lips; a stationary inclined chute below the bar-screen and substantially in line with it; a series of deflecting-wings in the chute extending from the sides downwardly part way across the bottom, the Wings on one side being midway between thosevon the opposite side and adapted to deflect the coal alternately from one side of the trough to the other; means secured to the lower end of the chute for suspending a bag below it; a removable screen below said bar-screen and inclined oppositely to it; an inclined spout below said removable screen and substantially in line with it; means secured to the lower end of said spout for suspending a bag below it; a stationary apron belowthe bar-screen and nearly parallel to it terminating above and near the top of the removable screen; a trough below the removable screen and inclined transversely to it and means secured to the lower end of said trough for suspending a bag below it.

In testimony whereof I amx my signature in presence of two witnesses.

JACOB H. GMELIN.
